17. In a pulse rate research, a simple random sample of 600 men results in a mean of 80 beats per minute, and a standard deviation of 11.3 beats per minute. Based on the sample results, the researcher concludes that the pulse rates of men have a stande deviation less than 12 beats per minutes. Use a 0.05 signicance level to test the researcher's claim. (a) Identify the null hypothesis and alternative hypothesis. (b) Determine the test Statistic. Show all work; writing the correct test statistic, without supporting work, will receive no credit. (c) Determine the P-value for this test. Show all work; writing the correct Pvalue, without supporting work, will receive no credit.
